Reaction Steps

[1-(2-{5-[6-(4-{2-[1-(2-tert-Butoxycarbonylamino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (0.211 g, 0.244 mmol) was dissolved in DCM (2.439 mL). HCl in dioxane (4N, 0.610 mL, 2.44 mmol) was added at room temperature and the resulting solution was stirred for approximately one hour. Upon completion, the reaction was concentrated in vacuo to giving [1-(2-{5-[6-(4-{2-[1-(2-Amino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester as a white solid (assumed 0.244 mmol) that was used without further purification in subsequent reactions. LCMS-ESI+: calc'd for C45H48N8O4: 764.43 (M); Found: 765.31 (M+H+).
